Numerical Predictions for Rising Water Levels in the Oceans

Igor G. Zurbenko, Amy L. Potrzeba-Macrina

World Scientific News > 2021 > 152 > 1-14

Global warming is an important and popular subject across global communities and in a wide array of literature. Global weather patterns are becoming more violent with an increase in the number of catastrophic events. The fundamental concepts of climate are strongly related to the natural freezers on planet Earth. Global warming affects Earth’s natural ice freezers. The warming climate in the Arctic...

Numerical Predictions for Global Climate Changes

Amy L. Potrzeba-Macrina, Igor G. Zurbenko

World Scientific News > 2020 > 144 > 208-225

Solar irradiation is the major source of energy delivered to Earth’s atmosphere. Satellite measurements of total solar irradiation are proportional in time to sunspot numbers. Sunspot numbers have a well-organized periodic nature that is predictable in time. At the present time solar activity is in a very low phase and will be increasing over the next few decades. The atmosphere’s consumption of solar...

Analysis of Regional Global Climate Changes due to Human Influences

Igor G. Zurbenko, Amy L. Potrzeba-Macrina

World Scientific News > 2019 > 132 > 1-15

In recent years global climate change has been the focus of much scientific research as well as a focal point in the media. A recent period of significant increases in global temperatures has caused much concern. This period was followed by a relative slowdown, which in turn has created confusion. There are two major reasons for global temperatures variations, one of which is oscillations of total...

Solar Energy Supply Fluctuations to Earth and Climate Effects

Igor G. Zurbenko, Amy L. Potrzeba-Macrina

World Scientific News > 2019 > 120 > 2 > 111-131

A major source of energy on Earth is solar irradiation. This paper uses the Kolmogorov-Zurbenko filter to smooth and examine sunspot numbers and proves that solar irradiation levels near Earth are strictly proportional to sunspot numbers. This paper also examines the transport of that energy through the atmosphere to Earth’s surface. Long term air temperatures on the surface of Earth perfectly follow...

Kolmogorov–Zurbenko filters in spatiotemporal analysis

Igor G. Zurbenko, Devin Smith

Wiley Interdisciplinary Reviews: Computational Statistics > 10 > 1 > n/a - n/a

This paper is an extension of WIRE publication Kolmogorov–Zurbenko filters, 2010. It addresses computational aspects of multidimensional KZ filtering for unevenly spaced data. Some real examples are provided to illustrate some of the details of such data analysis. The identification and separation of different spatial or temporal scales in spatiotemporal data can provide essential improvements to...

Explanation of fluctuations in water use time series

Katerina G. Tsakiri, Igor G. Zurbenko

Environmental and Ecological Statistics > 2013 > 20 > 3 > 399-412

This paper presents techniques for studying the influence of the climatic and other variables for the explanation of the water use with an example of time series in Gainesville, Florida. A statistical methodology is described for separating the different time scale components in time series of water use, namely, long term component, seasonal component, and short term component. We analyze each component...

Tides in the atmosphere

Igor G. Zurbenko, Amy L. Potrzeba

Air Quality, Atmosphere & Health > 2013 > 6 > 1 > 39-46

Tides in the water are important for any kind of human activities at sea. They have a periodic structure caused by solar and lunar gravitational forces; the levels of the tides are provided everywhere along coastlines. Tables of tidal levels contain forecasted levels of tides and are of extreme importance. The atmosphere is considered a fifth ocean, and we are living at the bottom of it. Tides in...

Prediction of ozone concentrations using atmospheric variables

Katerina G. Tsakiri, Igor G. Zurbenko

Air Quality, Atmosphere & Health > 2011 > 4 > 2 > 111-120

This paper presents techniques for the prediction of ozone concentrations in Albany, New York. A methodology is described for the decomposition of the time series of ozone and other atmospheric variables into long-term, seasonal, and short-term variations. Solar radiation appears to be the main atmospheric factor for the explanation of the long-term component of ozone time series. The vector autoregressive...

Tidal waves in the atmosphere and their effects

Igor G. Zurbenko, Amy L. Potrzeba

Acta Geophysica > 2010 > 58 > 2 > 356-373

A method of high resolution periodic signal reconstruction has been developed and implemented into software algorithms. This method, that utilizes a narrow band-pass filter, permits the detection of tidal waves in the atmosphere. Our paper describes and reviews the strength of this method, commonly referred to as the KZFT algorithm. The focus of this paper is given to the recovery of tides in the...

Determining the main atmospheric factor on ozone concentrations

Katerina G. Tsakiri, Igor G. Zurbenko

Meteorology and Atmospheric Physics > 2010 > 109 > 3-4 > 129-137

This paper presents techniques for studying the influence of the atmospheric variables for the explanation of ozone concentrations. A methodology is described for separating the different time scale components in time series of ozone, namely, the global-term component which describes the long and seasonal variations, and the synoptic-scale component. We prove that the decomposition of the time series...

Assessing the impact of the acid deposition control program

Kevin L. Civerolo, Elvira Brankov, S. Trivikrama Rao, Igor G. Zurbenko

Atmospheric Environment > 2001 > 35 > 24 > 4135-4148

A goal of the acidic deposition control program in the United States has been to link emissions control policies, such as those mandated under Title IV of the US Clean Air Act Amendments (CAAA) of 1990, to improvements in air and water quality. Recently, several researchers have reported trends in the time series of pollutant data in an effort to evaluate the effectiveness of the CAAA in reducing...
